ABSTRACT:
A liquid ventilator having a dual loop, single pump configuration is disclosed. The liquid ventilator preferably utilizes two three-way valves for routing liquid from a reservoir in a regeneration apparatus and to a patient's pulmonary system, and back to the reservoir again. A controller controls the configuration of the three-way valves and the pump speed of the motor to allow user control over the parameters of inspiration and expiration.
